amiga-debug Visual Studio Code Extension

One-stop Visual Studio Code Extention to compile, debug and profile Amiga C/C++ programs compiled by the bundled gcc 13.2 with the bundled WinUAE/FS-UAE and GDB.

Overview

This fully self-contained extension will help you to quickly develop demos, intros, games, etc. for the Amiga 500, 1200, 4000. It supports C and C++, however no standard library is available. It comes with advanced productivity features like debug overlay, frame profiler, graphics debugger and size profiler.

Here's a video showing off all the new features of v1.1, including the frame profiler and graphics debugger: https://www.youtube.com/watch?v=gQ4tKisnr7Y

Quick-start

  1. Install the extension from the Visual Studio Code Marketplace
  2. (recommended) install the Microsoft C/C++ extension from the Extensions tab under Recommended
  3. Create a new empty project folder with File > Open Folder...
  4. From the command palette Ctrl+Shift+P select Amiga: Init Project
  5. (optional, but recommended)
    • either: open settings Ctrl+, and under Extensions > Amiga C/C++ Compile, Debug & Profile point Rom-paths: A500 to your Kickstart 1.3 ROM
    • or: open .vscode/launch.json and point "kickstart" to your Kickstart 1.3 ROM
  6. Hit F5 to build and run a minimal sample project
  7. If you prefer C++ instead of C, just rename main.c to main.cpp

Contributing

For development, just install the latest node.js LTS, create a new directory, clone the repository git clone https://github.com/BartmanAbyss/vscode-amiga-debug.git, then install the dependencies with npm install. To build, open the directory in VS Code and hit F5. You can then test the extension without building a .vsix. To build a .vsix, npm install -g vsce (once), and then vsce package. For better testing, install the Mocha Test Explorer extension. The tests should then show up in your Testing tab.

Development (Windows)

Here are the command-lines used to compile the external tools (We're building with MinGW on WSL on Windows 10/11 to c:\amiga-mingw\opt). Replace the 16 in make -j16 with your number of CPU cores
